1-1 FeaturesThe basic features of the Thermac E5J Temperature Controller are outlinedbelow.

Fuzzy Self-tuning When using a conventional temperature controller for ideal temperature control,it is necessary to adjust the PID constants of the temperature controller accord-ing to the controlled device. The Thermac E5J Temperature Controller incor-porates a fuzzy self-tuning function, thus allowing ideal temperature controlwithout any adjustment of the PID constants. The user needs only to set theE5J to the desired temperature for ideal temperature control.

Auto-tuning Auto-tuning is also available. It is useful when appropriate results are notobtained through fuzzy self-tuning. (Refer to Section 10 Auto-tuning.)

Event Input Function It is possible to select a set point out of a maximum of two set values on theE5CJ-B and four set values on the E5AJ-B via their event input terminalsfrom the PCs connected to these Temperature Controllers. The control opera-tion of the E5AJ-B via can be stopped with an event input signal.

Watertight Construction The E5J can be used in places where water is sprayed onto the E5J, be-cause the front panel of the E5J assures IP54 when the E5J is panel-mounted (except for front panel of the E5CJ, which assures IP50). If greater wa-tertightness is required, use the Y92A-N, a dedicated watertight cover (soldseparately).

The E5J incorporates an advanced PID function, which is also incorporated bythe Thermac X Temperature Controller. The advanced PID function preventstemperature overshooting the moment the Temperature Controller starts oper-ating, assures a short startup time, and performs ideal temperature control byquickly responding to external disturbances.

Output Units The E53-R Relay Unit, E53-Q, E53-Q3, and E53-Q4 Voltage Output Units fordriving SSRs, and E53-C3, E53-C3D, E53-V34, and E53-V35 Linear OutputUnit can be connected to any E5J Temperature Controller (except the E5CJ)with ease according to the desired output configuration and application.

o Output Value Display The output value is displayed within a range of 0.0% to 100.0%.

cp Control Period Setting It is possible to set the control period within a range of 1 to 99 s. The control peri-od is the period required by the E5J to turn ON and OFF its relay output or volt-age output. The ON period increases in proportion to the output value. If the con-trol period is short, smooth control operation will be possible although a shortcontrol period shortens the life of the relay if relay output is used. Therefore, thecontrol period should not be less than 20 s if relay output is used. The followingare output examples with an output value of 50.0 %.

After the input shift value is set, the it is effective even if the input shift value dis-play is turned off on the engineering level.

It is possible to set the heater current value within a range of 0.0 to 55.0 A. If thecurrent value exceeds 55.0 A, ffff will be displayed on the set value display.The heater current will be processed and displayed if the control output is ON.

It is possible to set the heater burnout alarm value within a range of 0.0 to 50.0 A,which will be used to detect heater burnout. If the heater burnout alarm value isset to 0.0 A, the heater burnout alarm output will be always OFF. If the heaterburnout alarm value is set to 50.0 A, the heater burnout alarm output will be al-ways ON. Refer to Section 8 Heater Burnout Detection for details.

When the E5J is in advanced PID with fuzzy self-tuning mode, the followingparameters (p, i, d, ofr) will not be displayed (i.e., there is no need to set thefollowing parameters). The fuzzy self-tuning always adjusts the PID constants tothe most suitable values according to the characteristics of the controlled de-vice.

4-1 Fuzzy Self-tuning OperationThe fuzzy self-tuning function has three features, step response tuning (SRT),disturbance tuning (DT), and hunting tuning (HT).

4-1-1 Step Response Tuning (SRT)SRT is used to obtain all PID constants using a step response method when theTemperature Controller starts operations.

SRT is also used when the set point changes value exceeding a set range whilethe Temperature Controller is operating. After SRT has been executed, no SRTwill be executed the next time the Temperature Controller starts operating, un-less the set point has been changed.

Set pointMax. tempera-ture slope R

Dead time L

In step response tuning, control is completely imposed step-wise to measure the maximum temperature slope (R) anddead time (L), and the most ideal PID constants for the de-vice are obtained from R and L.

When using the E5AJ-A2HBor E5EJ-A2HB, you can change the RUN/STOP setting to RUN via event input2 after supplying power to the load.Dead time will be measured from the time the Temperature Controller startsoperating. If a load such as a heater is turned on after the Temperature Control-ler is turned on, dead time longer than the actual value will be measured andinappropriate PID constants will be obtained. If an extremely large amount ofdead time is measured, the control amount will be set to 0% for a short period oftime before being returned to 100%, and the constants will then be retuned.Retuning is performed only for large amounts of dead time, so be sure to followthe precaution given above when starting operation.

Fuzzy Self-tuning Operation Section 4-1

29

SRT Startup Condition SRT will be ON if the following conditions are satisfied simultaneously when theTemperature Controller is turned on or the set point is changed.

At the time the Temperature Controllerstarts operating

At the time set point is changed

1) The set point at the time theTemperature Controller starts operatingis different from the set point used atthe time SRT was last executed (seenote).

2) The difference between the set pointand the process value at the time theTemperature Controller starts operatingis larger than the present proportionalband value (P) x 1.27 + 4.

3) The process value at the time theTemperature Controller starts operatingis smaller than the set point in reverseoperation and larger than the set pointin normal operation.

1) The new set point is different fromthe set point used at the time SRTwas executed last (see note).

2) The set point changing range islarger than the presentproportional band value (P) x 1.27+ 4.

3) The process value is in stablecondition before the set point ischanged.

4) A larger set point value is set inreverse operation and a smallerset point is set in normal operation.

Note The last SRT-executed set point is set to 0 before shipping and when changingfrom advanced PID control to advanced PID control with fuzzy self-tuning.

In order to prevent overshooting, the step controlled amount must be imposedcontinuously only while the present deviation is the same as or greater than thevalue obtained from the proportional band (P)1.27. The step control will not beapplied when the deviation becomes smaller than this value.

If the step control amount is applied before the maximum temperature slope (R)is obtained, SRT will not renew any PID constant. If the proportional band ob-tained from the R and L values that were measured before the imposition hadbeen completed is larger than the present proportional band, the PID constantswill be renewed because the measured value is in the direction towards the suit-able proportional band value, and the set point at that time will be the SRT-executed set point.

4-1-2 Disturbance Tuning (DT)DT is used to measure the control waveform and adjust the PID constants whenthe measured temperature becomes unstable. When there are control charac-teristic changes after the PID constants are refreshed with SRT or when the PIDconstants are not suitable to the object to be controlled because SRT was notexecuted, the PID constants will be adjusted with DT.

If there is overshooting at the time the Temperature Controller restarts operatingafter SRT has been executed, DT adjusts the PID constants so that the set pointresponse waveform will be as close as possible to the most ideal response wa-veform after it is deemed that there has been a characteristics change in the con-trol system.

After the process value reaches the set point and becomes stable, if the processvalue is disturbed and the disturbance exceeds the stable range, the distur-bance is regarded as external disturbance At the time of disturbance, DT mea-sures the external disturbance waveform and adjusts the PID constants so thatthe external disturbance waveform will be as close as possible to the most idealexternal disturbance response waveform.

The external disturbance response waveform is approaching tothe most ideal response waveform even if the same kind ofexternal disturbance reoccurs. The waveform will not, however,change if the most ideal PID constants are already set.

Stability judge-ment time

Startup Conditions of DT DT is used to monitor the control waveform if there is external disturbance orSRT does not work at the time the Temperature Controller starts operating or atthe time of set point change. If the measured waveform is not an ideal waveform,DT will be ON. If either one of the following conditions is satisfied, the controlwaveform will be monitored.

1, 2, 3... 1. SRT Startup conditions 3 and 4 on page 29 are satisfied but neither 1 nor 2 issatisfied.

2. There has been an external disturbance exceeding the stable range afterthe process value was in stable condition.

Note The stable range is set to 27°F with the E5J--F.

4-1-3 Hunting Tuning (HT)If there is hunting due to characteristics changes of the control system, HT isused to measure the hunting waveform and adjust the PID constants to sup-press the hunting.

Set point

Extreme value


Measurement ofhunting waveform


Startup Conditions of HT HT will be ON when there is hunting with four or more maximum temperaturevalues while SRT is not being executed.

Note If the periodic temperature changes of the application exceed the stable range(set to 15.0°C at the factory) due to continuous external disturbance (i.e., thetemperature is affected by an external disturbance before stabilizing after a pre-vious external disturbance (refer to figure A below)), the user should change thestable range to a value greater than the temperature changing range, otherwise

DT at the Time of ExternalDisturbance Response

4-2 TroubleshootingFuzzy self-tuning may not exhibit its full capability due to the characteristics andconditions of the controlled object.

Refer to the following table for troubleshooting when Unit operation is notsmooth.

Phenomenon Probable cause Countermeasure

The temperature does not reach theset point.

The dead time measured was longerthan the actual value andinappropriate PID constants wereobtained because the load (such as aheater) was turned on after theTemperature Controller startedoperating. (Refer to 4-3-6 Startup fordetails.)

Do the following to execute SRTagain.

1) Set the control mode to theadvanced PID and set theproportional band to 0.1°C.

2) Set the control mode to theadvanced PID with fuzzyself-tuning again.

3) Wait until the temperature of thecontrol system is stable, and thenturn on the Temperature Controllerand the load simultaneously orturn on the load first for SRT.

The PID constants were changed fromthe most ideal value because HT isON continuously when there was aperiodic temperature change largerthan the stable range due to anexternal disturbance. Refer to the noteunder 4-1-3.

Do either one of the following so thatHT will not be ON.

• Change the stable range to awider setting than the range of thetemperature change and executeSRT again by executing steps 1)to 3) above.

• After obtaining the most ideal PIDconstants by executing steps 1) to3) above, set the control mode toadvanced PID.

Troubleshooting Section 4-2

32

Phenomenon CountermeasureProbable cause

Hunting does not stop. The control period is too long for thecharacteristics of the controlleddevice, which causes hunting insynchronization with the controlperiod.

Shorten the control period.

The temperature is influenced bycontinuous external disturbance (i.e.,the temperature is affected by anexternal disturbance before a previousdisturbance has be stabilized. and itlooks as if hunting did not stop at all).

In this case, however, 100%improvement will not be possiblebecause the temperature is influencedby a continuous external disturbanceinstead of hunting. Change the stablerange to a wider setting than therange of the temperature change sothat HT will not be ON.

The response fluctuates, becominggood and bad.

There is a heater or cooling device notcontrolled by the control output of theTemperature Controller (e.g., forcedheating or cooling is executed usingalarm outputs).

In this case fuzzy self-tuning may notwork. Set the control mode to theadvanced PID and adjust the PIDconstants manually.

The response fails to reachoperational requirements.

There are continuous characteristicschanges.

Do either one of the following.

• Adjust the stable range so thatfuzzy self-tuning will not be turnedON.

• Set the control mode to theadvanced PID and adjust the PIDconstants manually.

The response speed of the controlleddevice is so fast that it cannot beretrieved by a sampling period of 500ms.

The Thermac E5J TemperatureController cannot support a samplingperiod of less than 500 ms. Use anES100-series Digital controller, whichhas a shorter sampling period.

The temperature is affected bydevices near the system.

Fuzzy self-tuning does not supportany countermeasure againstinterference. Set the control mode tothe advanced PID and adjust the PIDconstants manually.

4-3 Terminology

4-3-1 Stable Value, Stable Range, and Stability Judgement Time

If the measured value continuously coincides with the set point, it can be saidthat the measured value is stable. The measured value will not continuouslycoincide perfectly with the set point if there is noise inference. It is, however, pos-sible to make the measured value stay within a permissible range called thestable range. Even if the temperature is within the stable range, the TemperatureController may respond to external disturbance or hunting. Therefore, it cannotbe said that the temperature is stable unless the temperature stays within thestage range continuously for a certain time. This time is called stability judge-ment time. Like PID constants, stability judgement time is adjusted with fuzzyself-tuning according to the characteristics of the object to be controlled. Fuzzy

Terminology Section 4-3

self-tuning will not be activated if the temperature is stable because the Temper-ature Controller deems that temperature control is smooth.

4-3-2 HuntingIf the PID constants are not suitable to the controlled device, the measured valuewill fluctuate and will not coincide with the set point, this phenomenon is calledhunting. Hunting is also called cycling.

Set pointSet point

4-3-3 Characteristics and Characteristics ChangeThe angle of the maximum temperature slope (R) of the controlled device (i.e.,whether the temperature rise of the device is fast or slow) and the dead time (L)of the controlled device (i.e., how fast the change in the output of the Tempera-ture Controller influences the temperature) vary with the characteristics of thecontrolled device. The PID constants must be set according to the characteris-tics of the controlled device. A characteristics change is the change of the char-acteristics of the controlled device due to the change of its thermal capacity andthe change of the supply voltage. If there is a characteristics change, the PIDconstants must be adjusted according to the new characteristics.

4-3-4 External DisturbanceExternal disturbance is an external factor that disturbs the temperature that hasbeen stable within the most ideal PID constants for the controlled device.

4-3-5 InterferenceIf devices, such as heaters, controlled by different temperature controllers arephysically close to one another, the heaters are mutually influenced and the tem-perature of each heater are affected. This phenomenon is called interference. Ifthere is serious interference, it will be difficult for each temperature controller tocontrol the device, and special controlled methods taking this interference intoconsideration will be required.


34

4-3-6 StartupStartup means that the Temperature Controller starts operating. The followingconditions are required to operate the Temperature Controller.

• The Temperature Controller must be turned ON.

• No sensor error has occurred.

• If a model with event input 2 is used, event input 2 must be set to RUN.Event input 2 is set to RUN before shipping.

The Temperature Controller will not start operating until all the above conditionsare satisfied.

The input polarity is wrong or theconnection is wrong.

Properly wire the terminals.

The input-type setting is incorrect. Properly set the input with theinput-type selector.

No compensating lead wires are usedfor the extension of the thermocouple.

Use proper compensating lead wires.

The thermocouple and E5J isconnected via wires other than properlead wires.

Use a dedicated thermocoupleconnector. If a metal material differentfrom the thermocouple is used toconnect the thermocouple and E5J,a temperature error may result.

The sensor is broken orshort-circuited.

Use a good sensor.

The E5J is influenced by noise orother induction.

Separate the input wires as far aspossible from the origin of the noise.

°C is used instead of °F or vice versa. Use the proper temperature unit.

The process value is shifted becausethe input shift function is used.

Set the input shift value to 0.

No control output is obtained. No Control Output Unit is connected. Connect a Control Output Unit (soldseparately).

Event input 2 of the E5J is set toSTOP.

Open event input 2 and set the E5Jto RUN.

The heater burnout detecting functionis abnormal.

No Current Transformer (CT) is used. Properly connect the dedicatedE54-CT1 or E54-CT3 (soldseparately) to the E5J.

The heater burnout alarm value is notproper.

Set the proper heater burnout alarmvalue taking into consideration thefluctuation of the heater supplyvoltage and measurement error.

The heater is turned ON or OFF withan output other than the controloutput.

Use the control output. Heater burnoutdetection synchronizes with thecontrol output. Any other outputcannot be used.

Simple Method to Determine Temperature Controller Error or Sensor ErrorWhen Thermocouple is Used If the temperature displayed by the E5J is close to the room temperature when

the input terminals of the E5J is short-circuited, the E5J deemed to be normaland it is presumed that the sensor is broken, short-circuited, or incorrectly wired.

If the temperature displayed by the E5J is close to 0.0°C when a resistor with aresistance of approximately 100 Ω is inserted between terminals A and –B of theE5J and terminals +B and –B of the E5J are short-circuited, the E5Jdeemed to be normal and it is presumed that the sensor is broken, short-cir-cuited, or incorrectly wired.

8-1 Heater Burnout DetectionTo detect heater burnout, wire one of the lead wires for each heater through thehole of the Current Transformer (CT). The CT generates an AC current accord-ing to the current flow of the lead wire. The Thermac E5J Temperature Control-ler measures the AC current to check the current flowing to the heater. If any oneof the heaters burns out, the AC current value will decrease so that the E5Jturns its heater burnout alarm ON, comparing the AC current value with the heat-er burnout alarm value.

8-2 Heater Burnout ProceduresThe E5J starts heater burnout detection from the moment the E5J is turnedon. If any one of the heaters is turned on after the E5J is turned on, the heaterburnout alarm output will be ON because the E5J judges that the heater isburnt out. Therefore, all the heaters must be turned on simultaneously with theE5J or before the E5J is turned on. This is essential for smooth temperaturecontrol and fuzzy self-tuning.

The E5J will continue temperature control even if the heater burnout alarm isON because the E5J will continue temperature control using the heaters thatare not burnt out.

Heater burnout detection is possible when the control output is ON. No heaterburnout detection is, however, possible if the control output is ON for less than190 ms.

The heater burnout alarm output will be held once the heater burnout is de-tected. To reset the heater burnout alarm output, replace the burnout heater witha good one and take one of the following steps.

1, 2, 3... 1. Set the heater burnout alarm value to 0.0 A.

2. Turn the E5J off and on.

If the difference between the normal heater current value and heater burnoutcurrent value is comparatively small, heater burnout detection will not be stable.For stable detection, the difference must be 1.0 A minimum if the heater currentconsumption is less than 10.0 A and 2.5 A minimum if the heater current con-sumption is 10.0 A or more.

Heater burnout detection is not possible if the E5J has current output, theheater current is DC, or three-phase heaters are used.

Use the K2CU-FA-GS (with gate input terminals) for three-phase heaterburnout. Refer to the K2CU-FA-GS data sheet specifications for details.

If no heater burnout detection is executed or if no CT is used, set the heater burn-out alarm value to 0.0 A. The heater burnout alarm value is factory-set to 0.0 A.

8-4 Heater Burnout Alarm ValueTo obtain the proper heater burnout alarm value, check the normal heater cur-rent value and heater burnout current value with the heater current value displayon display level 1 first and set the heater burnout alarm value to the mean valueof these two values. If more than one heater is used, check the burnout value ofthe heater with the smallest current consumption value.

If the difference between the normal heater current value and heater burnoutcurrent value is comparatively small, heater burnout detection will not be stable.For stable detection, the difference must be 1.0 A minimum if the heater currentconsumption is less than 10.0 A and it must be 2.5 A minimum if the heater cur-rent consumption is 10.0 A or more.

If normal current value 10.0 AThen normal current value – heat burnout current value 1.0 A

If normal current value 10.0 AThen normal current value – heater burnout current value 2.5 A

The heater burnout alarm value can be set within a range of 0.0 to 50.0 A. If thealarm value is set to 0.0 A or 50.0 A, no heater burnout detection is possible. Thealarm output is always OFF if the alarm value is set to 0.0 A and always ON if thealarm value is set to 50.0 A.

Heater Burnout Alarm Value Section 8-4

52

The normal heater current value should be 50.0 A max. The heater current valuecan, however, display up to 55.0 A. If the current value exceeds 55.0 A, CT inputoverflow will result and ffff will be displayed.

8-4-1 Setting ExamplesExample 1 In this example, 1-kW, 2-kW, and 3-kW heaters at 200 VAC are connected in par-

allel.

1, 2, 3... 1. Turn the control output ON and check the normal heater current value fromthe heater current value display.

Normal current = (1000 + 2000 + 3000) 200 = 30.0 A

Heater current value display


Normal current – heater burnout current = 30.0 – 25.0 = 5 A ( 2.5 A)

3. Set the heater burnout alarm value to the mean value of the normal currentvalue and heater burnout current value.

Heater burnout alarm value = (30.0 + 25.0) 2 = 27.5 A

Example 2 In this example, 400-W, 1700-W, and 2000-W heaters at 200 VAC are con-nected in parallel and the difference between the normal current value and heat-er burnout current value is less than 2.5 A.

1, 2, 3... 1. Obtain the normal current value and heater burnout current value in ad-vance as follows:

Normal current = (400 + 1700 + 2000) 200 = 20.5 A

Heater burnout current = 20.5 – 400 200 = 18.5 A

Normal current – heater burnout current = 20.5 – 18.5 = 2.0 A (Stable detec-tion is not possible because the value is not 2.5 A or more.)

2. For stable hater burnout detection, in such a case, increase the number ofturns of the wire passing through the CT as if apparent current value in-


53

creases. The displayed heater current value increases in proportion to thenumber of turns of the wire passing through the CT.

Heater wire

The wire passesthrough the CTtwice.

3. Obtain the heater burnout alarm value using the method in example 1.

Apparent normal current = (400 + 1700 + 2000) 200 x 2 = 41.0 A


Apparent heater burnout current = (41.0 – 400 200) x 2 = 37.0 A


Normal current – heater burnout current = 41.0 – 37.0 = 4.0 A ( 2.5 A)

Heater burnout alarm value = (41.0 + 37.0) 2 = 39.0 A

By setting automatic return of display mode, the display will return to the normaloperation display (on level 0 displaying the process value or set point) if no key isoperated for the time set with this parameter. The return time can be set within arange of 0 to 99 s. If the return time is set to 0 s, this function will not work. Thereturn time is set to 0 s before shipping.

It is possible to select the restart conditions of the standby sequence of the alarmattached with standby sequence. If this parameter is set to 0, the standby se-quence will restart when the set point, alarm value, or input shift value ischanged or the moment the E5J starts operating including the moment theE5J is turned on. If this parameter is set to 1, the standby sequence will restartonly the moment the E5J is turned on. The following timing chart is an exampleof a lower limit alarm attached with standby sequence.
